Eccentric Guide Post
There is an eccentric on the lower end of the guide post where the the guide assembly attach- es. This is held to the post by a setscrew and can be loosened and tightened with an Allen® wrench.
Figure 15A.
The eccentric allows the upper blade guide assembly to be moved to accommodate various blade sizes and wheel configurations.
Loosen the knob on the guide post. Rotate the guide block assembly on the guide post so the blade is directly in the center of the guide block legs. Retighten the knob and make sure the assembly didn’t move. If needed, adjust the eccentric on the post to make the assembly accommodate the blade.

Guide Blocks
For optimum support, the guide block assemblies should be adjusted so they are just behind the gullet line (the hollow points) of the blade. To adjust the guide block assemblies, loosen the thumbscrews securing the guide block yoke assemblies. Move in or out in relation to the blade gullets. Once adjusted, retighten the thumbscrew.
Now adjust the guide blocks. Loosen the guide block thumbscrews and adjust each block so it is about 0.004" from the blade. This is about the same thickness as a piece of typing paper. Retighten the thumbscrews and turn the upper wheel by hand through a complete revolution of the blade length to ensure that the blade weld passes through the guide blocks unhindered.
